9, Claims. (c1. 51-211) This invention appertains to new and usefulimprovements in the art of abrading, and more particularly to a novelstone holder.

The principal object of this invention is to provide a stone holderwherein the stone is' revolvable in oil or some other suitablelubricant. Another important object, of the invention is to provide astone holder wherein the stone will'always be maintained suflicientlylubricated, and cleaned or washed oi adhering particles caused byabrading.

Anotherv important objectof the invention is to provide a stone holderprovided with means whereby the stone can be retained in the desiredangular position to suit convenience, such as for presenting theabrading surfaces for abrading of a tool or other object and forpresenting said surfaces to the oil for lubricating the same and forcleaning or washing the same of adhering 90 particles mentioned above.

Other important objects and advantages of the invention will be found inthe following specification and claims.

In the drawings:---

Figure 1 represents a perspective view of the novel unit.

Fig. 2 represents a perspective view of the stone proper.

Fig. 3 represents a cross sectional view of the assembly.

Fig. 4. represents a longitudinal sectional view through the assembly.

Fig. 5 represents atop plan view of the stone holder. Fig. 6 representsa cross sectional view of the "assembly.

ferring to the drawings wherein like numorals designate like parts, it"can be seen that the invention includes a rectangular shaped trough orcontainer 5 having a circular opening 6 in one end wall thereof and avertically disposed slot 2 in the opposite end wall thereof.

Numeral t represents the elongated stone having the slabs a-a secured.to a pair of opposite in Fig. d The threaded pintle is disposed throughthe slot 7' while the smooth pintle is disposed through the one s. awinged nut 11 is engageable on the threaded pintle and adapted to be"tightened against the adjacent end of the trough 5 for securing thestone 8 in a suitable or predetermined position convenient to the user.

Numeral 12 represents the oil which is prei- 'erably of a baseless valueand which always has the stone 8 with its lowermost iace immersedtherein.

Obviously, the stone can be retained against rotation by the winged nut11 and when desired, the winged nut can be released and the stone movedor rotated to the desired angular position, whereupon the winged nut canbe again tightened for securing the stone in the angularly set position.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes inthe shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as planned hereinafter.

Having thus described my invention, what I claim as new is:

l. A stoneholder comprising a frame, a ,stone provided with a pintle ateach end thereof, said frame being provided with an opening at each endthereof for receiving the corresponding pintles, one of said pintlesbeing provided with threads and aunt seatable on the threed pintle andagainst the frame to bind the adjacent end of the stone against theirameto prevent rotation-thereof, the opening at oneend of the irethrough which the threaded pintle extends being in the form of a notchlaterally through which the threaded pintle may readily be removed whenthe nut is loosened.

'2. An abrading device comprising a. receptacleconstructed and arrangedto maintain a body oi oil of substantial depth therein, a stone; pintlesembedded in and projecting from the end portions as of said stone inline with the axis thereof, said pintles being rotatively mounted in theupper portions of the end walls of said receptacle in such manner thatthe stone is rotatable within the receptacle, and a clamp member, one ofpintles and said clamp member having complemental means constructed andarranged to tightly hold the contiguous end of the stone innon-rotatable frictional engagement with the 1% inner surface of theadjacent end wall, said box, said stone and said pintles being sorelatively positioned and arranged that as the stone rotates the facesthereof will be lubricated d i also washed of foreign particles, andportions no of the stone are submerged in the oil while the stone is atrest. v

3. An abrading device comprising a receptacle constructed and arrangedto maintain a body of oil of substantial depth therein, a stone having aplurality of sharpening faces, pintles projecting from the end portionsof said stone in line, with the axis thereof, said pintles beingrotatahly mounted inthe upper portions oi the end walls of saidreceptacle in such 7-"- :m that the stone may be rotated in a completecircle to selectively bring said surfaces to the top of the receptacle,and a clamp member, one of said plntles and said eaaeaa clamp memberhaving complemental means constructed and arranged to tightly hold thecon tiguous end of the stone in non-rotatable fricwith one of said facesin an approximately hori- 20mm plane at th t Jam
